Well Iggy, I have no idea how much farther you plan to go with this "how to" guide but from what I just read, you have done a fantastic job so far. You might even consider putting it up for sale to new folks to the flea market/farmer's market venues. What not make a buck off of it if you can and help others at the same time? Just my opinion. Anyway, keep on writing. It's very interesting. And as a side thought, you might even consider doing some video'ing on one of your events.
